    They might be 19mm but a 3/4 works great

    Also don’t forget the big hex key for the one under the sacrificial anode, 10mm I believe.

    Really need to properly torque these fasteners when reinstalling. You will need Torque Adapters and a Torque Wrench.

    +100! These all need to be torqued to 55 lbs/ft with the correct tool(s).

    Blue Liquid Locktite on the allen-head bolt (underneath the anode).
